Battery-powered pump
Submitted by flobbly on Tue, 11/08/2011 - 17:40
I've heard there's an RBP user (perhaps Matt?) who's rigged up a small electric pump in a plastic ski, and I'd be grateful to know how you did it. I'd like to replace the very inefficient foot pump in my recently bought Buzzard 'sit-on K1'. cheers...

Flobby- Electric pump in PRS
I have made up a small installation sheet showing how to do the install n a PRS with photo's etc.
If you send me an email I will send it to you.

Under the pump (repost)
(reposted to this more appropriate thread)
My pump is a Johnson L650 (nominal 600 litres per minute, 3/4" fittings). The pump is just right, works really well.
The battery is installed inside the boat in a water resistant bag. I use a switch on the inspection hatch, which I hit with my paddle. That seems to work well too, I have been warned about automatic switches playing up.
I first ran it on a small 2.5 Ahr Sealed Lead Acid battery (SLA). Like a small motorbike battery. This worked well and is fairly cheap (no fancy chargers). However, these are heavy and pretty basic.
I then upgraded to a 3S Lithium Polymer (LiPo) 11.1V Ahr battery. Like a remote control car battery. Much lighter and the slightly lover voltage is still fine. However, if you don't know about caring for and charging LiPo batteries ... don't go there! There are plenty of good youtube videos out there on how to blow up a LiPo battery!
